INVENTOK BY W Y ATTORNEY tiara COOLING SYSTEM FOR HENRY HUEBER, OF SEATTLE, WASHINGTON, ASSIGNOR T0 ARNOLD A. BARKLEY,

AUTOMOBILES.

Application filed February 12, 1917.

To all whom it may concern:

Be it known that I, IIEXRYQFIUEIEEH, a citizen of the United Fitates, residing at Seattle, in the county .i11g and State of Washington, have invented certain new and useful Improvements in Cooling Systems for Automobiles, of which the following is a specification.

his invention relates to improvements in cooling systems for automobiles and has for its object the provision of means for increasingthe rapidity of circulation of the Water by tl'1eunol'orwater jacket through maintaining a partial vacuum ni... n said radiator or the discharge point of the heated Water from the said gwalcr jacket, and the introduction of air within the water circulating system at the intake point of the circulating water within said water jacket. 7 With these and other ohjcctsin view, the invention consists in the novel construction adaptation and combination of parts of a Water circulating system, as will be fully described in the following specification,

illustrated in the acconuianying drawings, and pointed outin theappended clann.

In said drawings. Figure 1 is a view partly inside elevation and partly in vertical section of apparatus einliiodying my in- Vention as applied toan automobile.

' Fig. 2 is a similar view to Fig. 1, viewing the same from the (lii'unotrically opposite side of the automobile.

Figs. 3 and 4- are longitudinal sectional views of detailsof'lhe invention.

Referring to said views. the reference nu Ineral 1 indicates the body frame of an automobile and 2 a radiator of suitable form for cooling the water cmphrved in the water jacket of the motor 3. 5 indicates the upper Water circulating pipe connecting .sa id water jacket With the radiator, and 6 llli'. lower Water circulatingpipe connecting the lower portion of said radiator with the inlet to said jacket. 7 indicates the fillingneck whereby Water is introduced into the ra. diator, and 8 a threaded cap or closure therefor. Said cap provided with a relief valve of any suitable form illustrated as consisting in a ball 1!) conlined within a chamber 11 and adniiltinp of air or vapor passing outwardly through the holes l2 and 13, but not adn'i'ittlng air within the radiator.

15 indicates a pipe communicatively com nected at one end with the interior of the ,Specification of Letters Patent.

l radiator above the water line thereof and illustrated herewith as extending into said neck 7. A funnel-shapwl guard l l is posilloncd in the neck-'7 to prevent water, when introduced within the radiator, entering said pipe 15. The other end of said pipe 15 terminates in a nozzle ll extended within the bore of the pipe IT connectinp the carburetor J8 with the as intake n'iani'lold 20 of the motor. said nozzle 16 being positioned in the path of the gases passing through the pipe I? and pointingin the general direction in which said gases are moving.

2i indicates a valve of any approved type adapted to control the assa a'e of air or vapor through said connect ions l5. which valve is in the manual control of the driver by means ol a rod 22 which extends to the dash board 255 and is incascd in a llexible casing 25. i I

The pipe connections 4' are illustrated as entering the water jacket of the motor throug'lra header 20 into whi h one cxlrenr and is secured as atfiO. Said'extrcmity 38 extends into the stream ol water issuing" into said water jar-hot. and is directed in the general direction of said stream.

A bell member 5] and rigidly connected tosaid extremity 2b and at its opposite open end of considerably larger diameter than the bore of said eX tremity '38, projects forwardly of" said extremity into the stream of fluid.

Apcrtures 1-12 are formed in the circular wall of said hell admitting a considerable portion of said stream of water in pass through the bell and past the outlet f said extremity 28. The end of said tube 27 opposite to the glEXll'll'lJll) atmosphere for the admission-of air. with the exception that it is provided. with avalve. indicated generally by the numeral 9,3. which will prevent the passage of fluids therelhrough in a reverse direction. Said is desirably positioned above the water lever of the radiator.

movable valve member is held in yielding engagement with the valve seat through a light spring 36, the tension of said spring being barely sullicient to overcome the gravity of said valve member.

The operation of my invention may be described as follows: i

The current of gas par-icing; through the from the pipes ll 29 is open to the is reduced at one end pipe 1'? will create considerable suction in the nozzle 18 which is communicated through the pipe 15 as manually controlled by the valve 21, to the space above the water line in the radiator'il. The partial vacuum thus created will be effective to promote flow of Water throughout the circulatory system.

The stream of water flowing past the extrenuty :28 of the air inlet pipe 27 also pro-- duces an effect of suction within said pipe system.

If at times the pressure of air within the radiator above the water line exceeds the atmospheric pressure, such excess Will be relieved through the operation of the valve 10.

It is believed that the advantages'residing in my improved apparatus Will be clearly evident from the foregoing and par-. ticularly its simplicity and adaptability to practically all types of modern. automobilmi. The circulation of the cooling water through the motor water jacket has been demonstrated to be highly efficient and to necessita'te the throttling oi the suction generated through the pipe 15 by the partial closing of the valve 21,,as otherwise the water may be maintained at too low a temperature for ellicient economical working of the motor.

Among the other advantages aiforded by my invention is the introduction of aqueous vapor generated in the upper portion of the radiator through the pipe 15 into the manifold pipe 17, whence said vapor is introduced with the explosive gases int the engine cylinders, thereby assisting in the complete combustion of said gases and re ducing the deposit of carbon.

While I have described my invention with some detail, I do not wish to be understood as confining myself to the embodiment herein shown, but Wish to be limited only Within the scope of the appended claim.

\Vhat 1 claim, is

In a cooling system for automobiles, a

motor, a water jacket therefor, a radiator, inflow and outflow pipes coi'mecting the water jacket with the lower and upper portions oi said radiator, respectively, a gas intake pipe connected With the cylinders oi? said motor, a tube extending from the upper portion of said radiator lHllO' said intake pipe, said tube terminating within the latter in a nozzle disposed in the diregtion of the current of gas flowing through said intake. pipe to produce suction in said tube and a partial vacuum in said radiator adjacent said outflow pipe, an air inlet pipe c v '7 extending into the stream of water entering said water jacket to produce a suction in said inlet pipe, and a relief valvein said adiator.
